4G wireless data connectivity. Actually, in a world where most smartphones require a two-year contract, 4G basically now. Indeed, the wireless operator currently offers a number of 4G-compatible handsets, and the network is still being built, but it's safe to say that 4G is rapidly replacing the 3G as the fastest way to access the Internet wirelessly. Verizon has plans to cover virtually the entire network with 4G in 2013, and AT & T promised to upgrade the network and offer faster 4G to 80 percent of Americans in the same time frame. If you're in the market for a smartphone, a strong current to carry you through the next few years, you should consider a 4G handset is compatible.Phone and 4G networks are all not created equal. Verizon, for example, to use LTE for its 4G network. 4G LTE is currently the best in the land, and can provide download speeds are faster than the internet connection in your home. Sprint, on the other hand, is the first operator who entered the game with WiMAX 4G, and still use the standard. WiMAX to 3G rounds, but not nearly as fast as LTE. AT & T and T-Mobile uses the HSPA to 4G. AT & T plans to upgrade to LTE in the next two years, but currently using HSPA + 21, while T-Mobile is a faster move to HSPA + 42.
